Move the common test functions from cmd_test.go to cmd/testing/fake.go
**What this PR does / why we need it**:
This is so that we can use NewAPIFactory() from cmd/set/*test.go
Up until now we would get a import loop error.
This commit also adds a basic unit test case for cmd/set/set_image.go

This particular message isn't usually important, so demote it to glog.

Improvements to CLI usability and maintainability
Improves `kubectl` from an usability perspective by
1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.

attempt to use discovery RESTMapper and fallback if we can't
Updates `kubectl` to always attempt discovery regardless of server version. This is needed to extension servers.

Update run flags to point to generators docs
@janetkuo you've requested that in https://github.com/kubernetes/kubernetes/pull/32484#issuecomment-246840562 I'm opening this PR but like you I don't like the length of the descriptions already. The other problem with this is that there's not clean docs for a user to figure out what the generators are. I've stumbled upon this several times and I always found myself looking into the code :/ How about adding new flag/subcommand that will give you more information about generators and we'd move all those `--restart` and `--generator` information into specific generator info and present at the top level only general information?

Add 'kubectl set resources'
Add "kubectl set resources" for easier updating container memory/cpu limits/requests (for pods or resources with pod templates).
**Usage**
`kubectl set resources (-f FILENAME | TYPE NAME) ([--limits=LIMITS & --requests=REQUESTS])`
**Examples**
Set a deployments nginx container cpu limits to "200m and memory to "512Mi"
`kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi`
Set the limit and requests for all containers in nginx
`kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi`
Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
`kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml`
Remove limits on containers in nginx
`kubectl set resources deployment nginx --limits=cpu=0,memory=0`
